Projector or TV for a classroom?

Which three questions decide between a classroom projector and a TV?

Three questions decide between a classroom projector and a flat-panel TV. How far back the last row sits, because that sets the image size the room needs. How much daylight reaches the front wall, because a projected image depends on it. And whether the display stays in one room or travels between them.

Which display reaches the back row of a classroom?

A classroom display reaches the back row when its image is big enough from the furthest seat. Epson's 4/6/8 rule caps the viewing distance at four times the screen's vertical height for analytical viewing, six for basic presentations and eight for passive viewing such as video. A flat panel's height is fixed when you buy it; a projected image's height is set by where the projector stands.

That rule is what makes the panel's size ceiling matter. BenQ says “most of the screens used in interactive teaching are between 65 and 90 inches” — larger panels exist, but are not what classrooms usually buy — while projectors can “show a larger size screen simply by moving the projector farther back”. Neon+ publishes the V6 at a 1.2:1 throw ratio, a 39-inch frame at one metre, so one unit covers a small room and a long one (on neonplus.com.my).

The distances are arithmetic: a 16:9 diagonal converted to height, then multiplied by Epson's factors. BenQ lands in the same place — “a 100 inch display… for analytical viewing up to 16 feet away”, 4.9 metres against the table's 5.0. Our guide to how big a classroom projector image should be works the sum from your own back row.

What does classroom daylight do to a projector and a TV?

Daylight is the condition most likely to decide against a projector. BenQ states that projectors “rely on low ambient light to create contrast”, and that “the bright lights of a classroom lower the contrast on a projected image – making it harder to read”. A flat panel generates its own light rather than reflecting it off a wall.

Does daylight rule a projector out?

Only in a room whose blinds are never closed. A projector works in any classroom whose blinds are actually drawn for the lesson, at an image size its brightness can light; the honest test is whether a teacher will draw them every time. Indiana Wesleyan University's IT guidance puts the panel's side plainly: its image “is brighter than most projectors can achieve in a well-lit classroom or lab”. Neon+ publishes the V6 at 600 ANSI lumens; our guide to room light, image size and brightness (on neonplus.com.my) covers the trade.

Does a teacher cast a shadow on the image?

A teacher standing in the beam blocks a projected image, and a flat panel does not have the problem: Tech & Learning notes that with a projector “students or teachers block the projected image”. A panel has its own version. Indiana Wesleyan University notes it “can be adjusted manually to avoid glare from lights, or reflection of light from windows or doors” — direct glare a matt projection screen does not get as a reflection, though room light still washes a projected image out, as the daylight answer above says. Where the projector sits decides how often a shadow happens.

Does the classroom display need to move between rooms?

If the display has to move between rooms, that settles it in the projector's favour. A flat panel is mounted where it is installed, so one panel serves one room for its whole life. A portable projector goes to whichever classroom has the lesson.

Neon+ publishes the V6 at 786 g and 220 × 127 × 46 mm, with a tripod, remote, adapter, power cord and HDMI cable in the box. It has no built-in battery and runs from a 19 V / 3.42 A adapter, so every room it visits needs a power point within reach. Some other Neon+ models (the C2000, K5 and V8) are published with a built-in battery, which removes that constraint; the battery or externally powered guide (on neonplus.com.my) sets out the difference.

Sharing a travelling projector is a timetable job rather than a technical one: our guide to sharing one projector between classrooms covers the booking, the trolley and the pre-lesson checks.

Can pupils write on the screen?

Writing on the screen is the flat-panel TV's strongest case, and a projector on its own does not do it. BenQ describes interactive panels with “up to 40 points of touch, enabling multiple students to easily write on the screen at the same time”, though “the most popular models only enable six points of touch”.

The question for a school is how often the lesson needs it. Where pupils come to the front and annotate the screen daily, that is a panel job; where the display shows slides and video to seated pupils, the touch hardware is an expense the timetable never uses. Tech & Learning puts flat panels in “Study spaces designed for group projects and interaction” and projectors in “Large classrooms, study areas where ambient light can be controlled, lecture halls and band rooms”.

What do a projector and a TV cost to buy and to keep running?

A projector buys more screen for the money (about half the cost per screen size, on Tech & Learning's 2017 comparison); a flat-panel TV asks less of the people who run it. The purchase gap is the larger difference and it widens with size, because a panel's price climbs with its diagonal while a projected image grows by moving the projector back.

What is the purchase gap?

Both are vendor-adjacent views and both are dated (Tech & Learning is independent but its figure is from 2017; Epson sells projectors); with no verified current Malaysian panel price in our records, this guide compares categories rather than one product against another. Neon+ publishes prices per model; confirm them before a purchase order.

What does each need to keep running?

BenQ notes that “nearly every popular model of classroom projectors using LCD technology requires regular filter cleaning”. Neon+ publishes the V6 as a Texas Instruments DLP unit with an Osram RGB-LED light source, a different imaging category from the LCD models in that warning. The V6 specification Neon+ publishes does not say whether it has a filter, so ask. A flat panel has no filter and no light-source module to service, which is the upkeep argument for a panel. Our guide to how long a classroom projector lasts turns those hours into school years, and Neon+ warranty, delivery and support (on neonplus.com.my) sets out the 365-day local warranty.

So which should a Malaysian school buy, a projector or a TV?

A Malaysian school should buy the projector for a deep classroom with workable blinds: it is the only option, within the 65 to 90 inch panels BenQ says classrooms usually buy, that puts a 100-inch or larger image in front of the back row. It should buy the flat-panel TV for a small, permanently bright room where pupils write on the screen every lesson. Where there are more rooms than budget, one portable projector covers several timetables.

Write three measurements down before you shortlist a model:

1. metres from the front wall to the furthest seat,
2. how the room behaves with the blinds closed at 11am,
3. and how many rooms the display has to serve.

Those decide the category. Our guides to choosing a portable projector (on neonplus.com.my) and to setting up a classroom projector in Malaysia (on neonplus.com.my) take it from there.

Send us the room, not the model number. Tell the Neon+ team how far back your last row sits, how the room behaves with the blinds closed, and how many classrooms the display has to serve. They will tell you whether a projector is the right category for it, and which model fits. WhatsApp Neon+ on +60 12-565 2091 · Call +60 12-565 2091 · info@neonplus.com.my.

Neon+ is a projector specialist rather than a general display seller: a 365-day local warranty with 1-to-1 replacement for qualifying faults, free delivery above RM50 including Sabah and Sarawak, a showroom in Ipoh and branches in Kota Kinabalu and Sibu. ASEAN Records recorded 372 Neon+ portable smart projectors sold in May 2025, worth over RM1.41 million — one month's result, not a monthly rate. The Ipoh showroom opens 9am–5pm Monday to Friday and 9am–1pm Saturday; call ahead for the branches.
